11. What type of wave is produced when you move one end
down?
12. What type of wave has a wavelength?
13. Obtain a ruler and determine
the wavelength of the wave to the
right.

Wavelength =​

The highest point on a wave is the Crest_, while the lowest point is the Trough Get a ruler and measure the wavelength and amplitude of the above wave.  (a) Waves P and Q have the same frequency, but wave P has twice the  What type of wave is produced when you move one end of a horizontal spring up
